Quarkus GitHub Bot

A Quarkus-powered GitHub App to simplify issues and pull requests management in the Quarkus project.

Introduction

This GitHub App is based on the Quarkus GitHub App framework.

It can be run as a native executable.

Current Actions

Check pull request editorial rules

This action checks that the title of a pull request respects some editorial rules to make Release Notes more consistent.

Triage issues

Based on the .github/quarkus-bot.yml file, this rule affects labels to issues and also pings the appropriate people.

Syntax of the .github/quarkus-bot.yml file is as follows:

triage:
  rules:
    - labels: [area/amazon-lambda]
      title: "lambda"
      notify: [patriot1burke, matejvasek]
      directories:
        - extensions/amazon-lambda
        - integration-tests/amazon-lambda
    - labels: [area/persistence]
      title: "db2"
      notify: [aguibert]
      directories:
        - extensions/reactive-db2-client/
        - extensions/jdbc/jdbc-db2/

For issues, each rule can be triggered by:

• title - if the title matches this regular expression (case insensitively), trigger the rule

• body - if the body (i.e. description) matches this regular expression (case insensitively), trigger the rule

• titleBody - if either the title or the body (i.e. description) match this regular expression (case insensitively), trigger the rule

• expression - allows to write a Jakarta EL expression testing title, body or titleBody. Be careful when writing expressions, better ping @gsmet in the pull request when creating/updating an expression.

Tip

When writing expressions, you can use the matches(String pattern, String string) function that behaves as follows: public static boolean matches(String pattern, String string) { return Pattern.compile(".*" + pattern + ".*", Pattern.DOTALL | Pattern.CASE_INSENSITIVE).matcher(string) .matches(); } A rule using an expression based on matches() would look like: - labels: [area/hibernate-orm, area/persistence] expression: | matches("hibernate", title) && !matches("hibernate.validator", title) && !matches("hibernate.search", title) && !matches("hibernate.reactive", title) notify: [gsmet, Sanne, yrodiere]

If the rule is triggered, the following actions will be executed:

• notify - will create a comment pinging the users listed in the array

• labels - will add the labels to the issue

Triage pull requests

The pull requests triage action uses the same configuration file as the issues triage action.

There are a few differences though as it doesn’t behave in the exact same way.

For pull requests, each rule can be triggered by:

• directories - if any file in the commits of the pull requests match, trigger the rule. This is not a regexp (it uses startsWith) but glob type expression are supported too extensions/test/**.

If the rule is triggered, the following action will be executed:

• labels - will add the labels to the issue

• notify - will create a comment pinging the users listed in the array only if notifyInPullRequest is true

notifyInPullRequest should be used as follows:

triage:
  rules:
    - labels: [area/amazon-lambda]
      title: "lambda"
      notify: [patriot1burke, matejvasek]
      notifyInPullRequest: true
      directories:
        - extensions/amazon-lambda
        - integration-tests/amazon-lambda

Notify QE

When the triage/qe? label is added to an issue or a pull request, the QE team is pinged.

The configuration is done in the quarkus-bot.yml config file:

triage:
  qe:
    notify: [rsvoboda, mjurc]

Affect milestones

When a pull request is merged, if it targets the main branch, it affects the milestone ending with ` - main` to the pull request and the issues resolved by the pull request (e.g. Fixes #1234).

It only affects the milestone is no milestone has been affected prior to the merge. If the milestone cannot be affected, we add a comment to the pull request indicating the items for which we haven’t affected the milestone.

Workflow run report

When a workflow run associated to a pull request is completed, a report is generated and added as a comment in the pull request:

Mark closed pull requests as invalid

If a pull request is closed without being merged, we automatically add the triage/invalid label to the pull request.

Automatically remove outdated labels

The bot will automatically remove these labels when they are outdated:

• triage/needs-triage from closed issues

• waiting-for-ci from closed pull requests

Contributing

To participate to the development of this GitHub App, create a playground project in your own org and follow the steps outlined in the Quarkus GitHub App documentation.

GitHub permissions required:

• Actions - Read only

• Contents - Read only

• Issues - Read & Write

• Pull Requests - Read & Write

Events to subscribe to:

• Issues

• Pull Request

• Workflow run

• Workflow dispatch

By default, in dev mode, the Bot runs in dry-run so it’s logging its actions but do not perform them. You can override this behavior by adding _DEV_QUARKUS_BOT_DRY_RUN=false to your .env file.

Deployment

Once logged in to the OpenShift cluster (using oc login…​), just run:

$ ./deploy-to-openshift.sh
