Lock Threads is a GitHub Action that locks closed issues, pull requests and discussions after a period of inactivity.

The continued development of Lock Threads is made possible thanks to the support of awesome backers. If you'd like to join them, please consider contributing with Patreon, PayPal or Bitcoin.

Create the lock-threads.yml workflow file in the .github/workflows directory, use one of the example workflows to get started.

The action can be configured using input parameters.

The following workflow will search once an hour for closed issues, pull requests and discussions that have not had any activity in the past year and can be locked.

name: 'Lock Threads'

on:
  schedule:
    - cron: '0 * * * *'
  workflow_dispatch:

permissions:
  issues: write
  pull-requests: write

concurrency:
  group: lock-threads

jobs:
  action:
    runs-on: ubuntu-latest
    steps:

Edit the workflow after the initial backlog of issues, pull requests and discussions has been processed to reduce the frequency of scheduled runs. Running the workflow only once a day helps reduce resource usage.

on:
  schedule:
    - cron: '0 0 * * *'

This workflow declares all the available input parameters of the action and their default values. Any of the parameters can be omitted.

This step will lock only issues, and exclude issues created before 2018, or those with the upstream or help-wanted labels applied.

    steps:
      - uses: dessant/lock-threads@v5
        with:
          exclude-issue-created-before: '2018-01-01T00:00:00Z'
          exclude-any-issue-labels: 'upstream, help-wanted'
          process-only: 'issues'

This step will lock only pull requests, and exclude those with the wip label applied.

    steps:
      - uses: dessant/lock-threads@v5
        with:
          exclude-any-pr-labels: 'wip'
          process-only: 'prs'

This step will lock only issues, and exclude issues closed before 2018, or those created in 2018 and 2019.

    steps:
      - uses: dessant/lock-threads@v5
        with:
          exclude-issue-created-between: '2018-01-01T00:00:00Z/2019-12-31T23:59:59.999Z'
          exclude-issue-closed-before: '2018-01-01T00:00:00Z'
          process-only: 'issues'

This step will lock issues that have the incomplete or invalid labels applied, and pull requests that have the qa: done and published labels applied.

    steps:
      - uses: dessant/lock-threads@v5
        with:
          include-any-issue-labels: 'incomplete, invalid'
          include-all-pr-labels: 'qa: done, published'
          process-only: 'issues, prs'

This step will lock discussions that have not had any activity in the past 180 days.

    steps:
      - uses: dessant/lock-threads@v5
        with:
          discussion-inactive-days: '180'
          process-only: 'discussions'

This step will post a comment on issues and pull requests before locking them, and apply the outdated label to issues.

    steps:
      - uses: dessant/lock-threads@v5
        with:
          add-issue-labels: 'outdated'
          issue-comment: >
            This issue has been automatically locked since there
            has not been any recent activity after it was closed.
            Please open a new issue for related bugs.
          pr-comment: >

            has not been any recent activity after it was closed.
            Please open a new issue for related bugs.
          process-only: 'issues, prs'

This step will apply the qa: done and archived labels, and remove the qa: primary and needs: user feedback labels before locking issues.

    steps:
      - uses: dessant/lock-threads@v5
        with:
          add-issue-labels: 'qa: done, archived'
          remove-issue-labels: 'qa: primary, needs: user feedback'
          process-only: 'issues'

The action uses an installation access token by default to interact with GitHub. You may also authenticate with a personal access token to perform actions as a GitHub user instead of the github-actions app.

Create a personal access token with the repo or public_repo scopes enabled, and add the token as an encrypted secret for the repository or organization, then provide the action with the secret using the github-token input parameter.

    steps:
      - uses: dessant/lock-threads@v5
        with:
          github-token: ${{ secrets.PERSONAL_ACCESS_TOKEN }}

The action uses GitHub's updated search qualifier to determine inactivity. Any change to an issue, pull request or discussion is considered an update, including new comments, or changing labels.

An easy way to see which threads will initially be locked is to add the updated search qualifier to the issue, pull request or discussion search field for your repository, adjust the date based on the value of the *-inactive-days input parameter: is:closed is:unlocked updated:<2018-12-20.

To avoid triggering abuse prevention mechanisms on GitHub, only 50 threads will be handled at a time. If your repository has more than that, it will take a few hours or days to process them all.
