ER: Create shared artifact module for set-pr-label & pr-trigger #8844

Emergent Requirement - Problem

We need to create one shared module between set-pr-labels and pull-request-trigger workflows since both files have repetitive code.

Issue you discovered this emergent requirement in

• Specify default permissions for pull-request-trigger.yml and wr-pull-request-trigger.yml #8590

What happens if this is not addressed

If this remains unaddressed, then repetitive code will continue to bloat the overall codebase. We want to consolidate artifact handling functions into a single, shared utility file to minimize redundancy, improve consistency, and make it easier to maintain.

Recommended Action Items

• Make a new issue
• Discuss with team
• Let a Team Lead know

Potential solutions [draft]

We will split the solution into two issues. One issue will create the module and implement the change in the PR trigger workflow. The other issue will implement the change in the set PR labels workflow.

Issue 1

• Complexity: Large
• Relationships: Blocks issue 2
• Size: 0.5pt

Issue 1 Solution

• View the following workflows to understand how artifacts are integrated and how they work:
  • PR Trigger workflow
    • github-actions/trigger-pr/check-linked-issue.js
    • .github/workflows/pull-request-trigger.yml
    • .github/workflows/wr-pull-request-trigger.yml
  • Set PR labels workflow
    • github-actions/trigger-pr/set-pr-labels.js
    • .github/workflows/set-pr-labels.yaml
    • .github/workflows/wr-set-pr-labels.yaml
• In github-actions/trigger-pr/check-linked-issue.js and github-actions/trigger-pr/set-pr-labels.js, note the duplicate functions and understand how they work. These functions will be moved into a shared utility module:
  • _downloadArtifact
  • _listWorkflowRunArtifacts
  • downloadPRCommentArtifact/downloadLabelsArtifact
• Create a utility file called download-artifacts.js in github-actions/utils
  • Transform downloadPRCommentArtifact/downloadLabelsArtifact into one generic function, called downloadAndStoreArtifact
  • Keep _downloadArtifact and _listWorkflowRunArtifacts as private functions that will be called by downloadAndStoreArtifact
• Implement the new utility file into the PR trigger workflow
• In github-actions/trigger-pr/check-linked-issue.js:
  • Remove the deprecated artifact functions: _downloadArtifact and _listWorkflowRunArtifacts
  • Import downloadAndStoreArtifact by adding const downloadAndStoreArtifact = require('../utils/download-artifacts'); to the top of the file
  • Refactor downloadPRCommentArtifact to only call downloadAndStoreArtifact as a wrapper
  • Verify the workflow still runs as expected

Issue 2

• Complexity: Medium
• Relationships: Blocked by issue 1
  • Note, once both issues are created mark issue 2 as blocked by issue 1
• Size: 0.25pt

Issue 2 Solution

• View the following files to understand how the workflow executes and what needs to be refactored:
  • github-actions/trigger-pr/set-pr-labels.js
  • github-actions/utils/download-artifacts
  • .github/workflows/set-pr-labels.yaml
  • .github/workflows/wr-set-pr-labels.yaml
• Implement the download artifacts utility into the Set PR labels workflow
• In github-actions/trigger-pr/set-pr-labels.js:
  • Remove the deprecated artifact functions: _downloadArtifact and _listWorkflowRunArtifacts
  • Import downloadAndStoreArtifact by adding const downloadAndStoreArtifact = require('../utils/download-artifacts'); to the top of the file
  • Refactor downloadLabelsArtifact to only call downloadAndStoreArtifact as a wrapper
  • Verify the workflow still runs as expected
