Examples

The following workflow will search once an hour for closed issues and pull requests that can be locked.

name: 'Lock Threads'

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

jobs:
  lock:
    runs-on: ubuntu-latest
    steps:
      - uses: dessant/lock-threads@v2
        with:
          github-token: ${{ github.token }}

Edit the workflow after the initial backlog of issues and pull requests 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 * * *'

Available input parameters

This workflow declares all the available input parameters of the action and their default values. Any of the parameters can be omitted, except github-token.

name: 'Lock Threads'

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

jobs:
  lock:
    runs-on: ubuntu-latest
    steps:
      - uses: dessant/lock-threads@v2
        with:
          github-token: ${{ github.token }}
          issue-lock-inactive-days: '365'
          issue-exclude-created-before: ''
          issue-exclude-labels: ''
          issue-lock-labels: ''
          issue-lock-comment: ''
          issue-lock-reason: 'resolved'
          pr-lock-inactive-days: '365'
          pr-exclude-created-before: ''
          pr-exclude-labels: ''
          pr-lock-labels: ''
          pr-lock-comment: ''
          pr-lock-reason: 'resolved'
          process-only: ''

Excluding issues and pull requests

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@v2
        with:
          github-token: ${{ github.token }}
          issue-exclude-created-before: '2018-01-01T00:00:00Z'
          issue-exclude-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@v2
        with:
          github-token: ${{ github.token }}
          pr-exclude-labels: 'wip'
          process-only: 'prs'

Commenting and labeling

This step will post a comment on issues and pull requests before locking them, and apply the outdated label to issues.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@v2
        with:
          github-token: ${{ github.token }}
          issue-lock-labels: 'outdated'
          issue-lock-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-lock-comment: >
            This pull request has been automatically locked since there
            has not been any recent activity after it was closed.
            Please open a new issue for related bugs.

How are issues and pull requests determined to be inactive?

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

An easy way to check and see which issues or pull requests will initially be locked is to add the updated search qualifier to either the issue or pull request page filter for your repository: is:closed is:unlocked updated:<2018-12-20. Adjust the date to be 365 days ago (or whatever you set for *-lock-inactive-days) to see which issues or pull requests will be locked.

Why are only some issues and pull requests processed?

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