Review Gator

Review gator is an aggregate view of code reviews a team has to do.

It pulls github and launchpad for open review slots and generates a static HTML review queue, that can be hosted anywhere. Review Gator works with Launchpad (bazaar or git) or Github repositories.

Installation

The following steps should leave you with a working script:

virtualenv -p python3 --system-site-packages .venv
source .venv/bin/activate
pip install -e .
GITHUB_TOKEN=... review-gator --config branches.yaml

Basic Configuration

Configuration is provided via a YAML file. To see an example, run review-gator --config-skeleton

launchpad:
    owners:
        # Launchpad username
        LAUNCHPAD-USERNAME:
            max-age: 30
    branches:
        # Full path to repo
        LAUNCHPAD-BZR-REPO-PATH:
            review-count: 2
github:
    repos:
        GITHUB-USERNAME:
            GITHUB-PROJECT-NAME:
                review-count: 2
lp-git:
    owners:
        LAUNCHPAD-USERNAME:
            max-age: 30
    repos:
        LAUNCHPAD-GIT-REPO-PATH:
            review-count: 2
            parallel-tox: false
            environment: 18.04

Note: The code for the owners stanza is immature and requires more testing and development.

Configuration Explanation and Hierarchy

Hosting & Repository Type type:

• launchpad: Launchpad hosted bazaar repositories
• github: Github hosted git repositories
• lp-git: Launchpad hosted git repositories

Owners or Repos:

• owners: Checks for all MPs under an owners specfied below.
• repos: Check for MPs for listed repos

User or Repo

• $LAUNCHPAD-USERNAME: User to search for for MPs
• $REPO-NAME: Repository name for searching for MPs

Specific Configurations

• owners.$USERNAME.max-age: Int. Max age of the MP to show in search results
• repos.$REPO-NAME.review-count: Int. Number of reviewer boxes to display on an MP.
• repos.$REPO-NAME.tox: Boolean. Enable tox for a specific repository
• repos.$REPO-NAME.parallel-tox: Boolean. Run tox in parallel with other repos. Tox environments are also run in parallel.
• repos.$REPO-NAME.environment: String. If specified, use this ubuntu release in a lxc container (e.g. 16.04, 18.04, etc.)

Testing with Tox

Review Gator has the ability to run tox on all your Python based codelines. This can be enabled on a per repo:

github:
    repos:
        CanonicalLtd:
            review-gator:
                review-count: 2
                tox: true

Tox is run in parallel using --tox-jobs. By default, Review Gator will parallelize as many jobs as possible. If you'd like to limit parellization, pass an into to --tox-jobs to set the max number of jobs

Dedicated tabs

Review Gator has the ability to have a dedicated tab for special repos without being included in the default view our review-gator.

This is useful for repos that have a lot of review traffic and you want to have a dedicated tab for them.

This can be enabled on a per repo:

github:
    repos:
        CanonicalLtd:
            review-gator:
                review-count: 2
                tox: true
                tab-name: "Review Gator"

Tox is run in parallel using --tox-jobs. By default, Review Gator will parallelize as many jobs as possible. If you'd like to limit parellization, pass an into to --tox-jobs to set the max number of jobs

TODO

• Test owners stanza support to identify and document issues, and complete owners support
• Add unit testing.
