GameClay Workflow GitHub Post Receive Server

This is the workflow server that wires GameClay GitHub projects in to Lighthouse for specific git actions.

Managed Tickets

We can all agree that bug trackers are very useful, and that proper use of version control workflow is very useful. Previously, this included a lot of duplicated effort. When proper use of tools delays the development process on a repetitive basis, any benefit from those tools is harder to see. In order to allow a lead programmer to truly be both a lead, and a programmer Uttu introduces the concept of managed tickets to the project workflow. A managed ticket is kept automatically updated with information Uttu retrieves from GitHub, removing the need to duplicate work in both version control, and bug tracker.

For example: When someone adds a 'TODO' to your code, Uttu will find it and create a ticket for that task, including commit information. If that comment is later deleted, Uttu will resolve the ticket, and include applicable information.


Running the server will create a template config.yaml for you to fill in with the Lighthouse subdomain and API token. For more information on Lighthouse API tokens, please see: How do I get an API token?

When the server gets a Post-Receive hit from GitHub, it will use the repository name and attempt to find a corresponding Lighthouse project. If it cannot find the GitHub repository name in the config.yaml file it will insert it for you. Simply fill in the Lighthouse project ID.

All edits to config.yaml will apply the next request the server receives.

Lighthouse Configuration

  token: <lighthouse token>
  account: <lighthouse subdomain>

Project Configuration

  lighthouse_id: <corrisponding Lighthouse project id>
  merge_state: <state to mark tickets when Uttu detects a bug-fix merge>


Here is a sample config.yaml (no that is not a valid API token) --- LighthouseIntegrationTest: lighthouse_id: 123456 merge_state: resolved AnotherGitHubRepository: lighthouse_id: 987654 merge_state: fixed lighthouse: token: 71c6c325c4c3d631d09332e64a7acb22aabc65d3 account: mysubdomain

CI Joe

If you use CI Joe with a fork of this repository, and set it up as a Post-Receive hook, you can run a self-updating server.

First assign the CI Joe runner command $ git config --add cijoe.runner "rake -s install" This will install Uttu, making the new code that you just pushed to GitHub available at the user, or administrator level (we run Uttu in user mode).

Next create a build-worked hook in .git/hooks/build-worked: #!/bin/sh rake -s stop rake -s start This will restart Uttu if the rake install task succeeded; your Uttu server now reflects the changes you just pushed.


Uttu is tested using a GitHub repository which contains instances of all of workflow events that this server should detect. The repository gets 'repushed' to provide a way to deterministically test Uttu's interaction with Lighthouse. To do this easily, use a simple script. This is the meat of the script: git reset --hard some_commit # Return the repository to a previous state git push --force # Push with --force to return the origin index to the previous state git reset --hard HEAD@{1} # Restore the "last state" of our repository from the reflog git push # Push all commits to origin

More information can be found in our Lighthouse Integration Test Repository. The Lighthouse test project is also available here.

Workflow Tasks

Uttu looks for information in git commit messages. It then performs Lighthouse API tasks .

Bug Fix Branches

When Uttu sees a commit to the master branch with the message in the format: Merged branch 'initials/bug-#' It will mark the corresponding bug with the state specified in the project's merge_state; this defaults to resolved.

For example, a branch named pw/bug-3

GitHub graph of a branch called pw/bug-3

Will cause Uttu to modify the associated ticket.

Uttu will attempt to keep track of the TODO's you add to your code. A File Adding a TODO

When Uttu gets a commit that has a diff chunk which adds a line with the text "TODO" (and many variations), it will automatically create a task in Lighthouse that links back to the commit, and that file/line so that TODO tasks can be collected on the Lighthouse tracker. Uttu will also look for diff chunks where a TODO gets deleted, and will automatically resolve the associated ticket.

Feature Branches

Uttu looks for the addition of feature branches to the repository. When it sees the addition of a feature-branch, it creates a managed Lighthouse ticket
