GitHub hooks to provide an encouraging atmosphere for new contributors. Highfive assigns pull requests to users based on rules in configuration files. You can see Highfive in action in several Rust repositories. See the rust-lang/rust pull requests, for example.
This project drives the @rust-highfive bot and was originally a fork of servo/highfive, used by Servo and Servo's @highfive bot. For more history see the comments in #35.
Table of Contents
Installation
To install highfive
, you just need to execute the setup.py
script or use
pip
directly. Both commands have to be executed from the directory where
setup.py
is located.
$ python setup.py install
or
$ pip install . # the dot is important ;)
Testing
Before running tests, make sure the test-requirements are installed by running the following command:
$ pip install -r test-requirements.txt
Once the dependencies are installed, you can run all tests by executing:
$ pytest
Tests are labeled as "unit", "integration", and "hermetic". All unit tests are hermetic, but only some integration tests are hermetic. A non-hermetic test makes network requests. To run only hermetic tests do:
$ pytest -m hermetic
Hermetic tests are run in PR builds. All tests are run in daily cron builds.
Adding a Project
To make rust-highfive interact with a new repo, add a configuration file in
highfive/configs
, with a filename of the form reponame.json
. The file should look like:
{
"groups":{
"all": ["@username", "@otheruser"],
"subteamname": ["@subteammember", "@username"]
},
"dirs":{
"dirname": ["subteamname", "@anotheruser"]
},
"contributing": "http://project.tld/contributing_guide.html",
"expected_branch": "develop",
"mentions": {
"src/doc": {
"message": "Documentation was changed.",
"reviewers": ["@DocumentationReviewPerson"]
},
"test.rs": {
"message": "Some changes occurred in a test file.",
"reviewers": ["@TestReviewPerson"]
}
},
"new_pr_labels": ["S-waiting-for-review"]
}
The groups
section allows you to alias lists of usernames. You should
specify at least one user in the group "all". Other keys are optional.
In the dirs
section, you map directories of the repository to users or
groups who're eligible to review PRs. This section can be left
blank.
contributing
specifies the contribution guide link in the message which
welcomes new contributors to the repository. If contributing
is not
present, the Rust contributing.md will be linked instead.
If PRs should be filed against a branch other than master
, specify the
correct destination in the expected_branch
field. If expected_branch
is
left out, highfive will assume that PRs should be filed against master
.
The bot posts a warning on any PR that targets an unexpected branch.
The mentions
section is used by Highfive when new PRs are
created. If a PR diff modifies files in the paths configured in the
mentions
section, a comment is made with the given message that
mentions the specified users. Mentions paths have either one or two
behaviors.
- Every path in a diff is checked whether it begins with a path in the mentions list. If there is a match, the mention comment is made.
- If a path in the diff ends with a mentions path ending in
.rs
, the mention is a match, and a comment is made.
new_pr_labels
contains a list of labels to apply to each new PR. If it's left
out or empty, no new labels will be applied.
Enabling a Repository
Once the PR updating the repository configuration has been merged, run the
update-webhooks.py
script at the root of this repository:
$ python3 update-webhooks.py
The script requires the GITHUB_TOKEN
environment variable to be set to a
valid GitHub API token, and it will make sure the configuration of all the
repositories you have admin access to is correct.
Local Development
You can run Highfive on your machine and configure a repository to use your local instance. Here is one approach for running a local server:
- Create a virtualenv to isolate the
Python environment from the rest of the system, and install highfive in it:
$ virtualenv -p python2 env $ env/bin/pip install -e .
- Run the highfive command to start a development server on port 8000:
$ env/bin/highfive
- Your Highfive instance will need to be reachable from outside of your machine. One way to do this is to use ngrok to get a temporary domain name that proxies to your Highfive instance. Additionally, you will be able to use ngrok's inspector to easily examine and replay the requests.
- Set up the webhook by following the instructions in Enabling a Repo, substituting your local Highfive IP address or domain name and port number (if necessary).
- Obtain an OAuth token. In the account you are creating the token in, go to https://github.com/settings/tokens. Grant access to the repository scope.
- Put the authorization information obtained in the previous step into a file
named
.env
in the top of the repository (i.e., the directory containing this file). Here is a template of what it should look like:Do not check in this file or commit your OAuth token to a repository in any other way. It is a secret.HIGHFIVE_GITHUB_TOKEN=your-token
Here are some details to be aware of:
- For Highfive to know how to select reviewers for your repository, you need a configuration file in highfive/configs.
- Highfive ignores comments from the integration user near the top of
new_commment
in highfive/newpr.py.
Docker
Alternatively, you can build a Docker image that runs Highfive.
$ docker build -t highfive .
To run a container, you must mount a config file. Assuming you are launching a container from a directory containing a config file, you can do the following.
$ docker run -d --rm --name highfive -p 8000:80 -e HIGHFIVE_GITHUB_TOKEN=token -e HIGHFIVE_WEBHOOK_SECRET=secret highfive
At this point, Highfive is accessible at http://localhost:8080.
