Removes dependence on formatPipelinesGraphQLDataToREST method

Epic: MR Pipelines migration to GraphQL (&14144) • Sahil Sharma • 18.7

Issues:

• Apollo MR pipelines - Add manual actions (#467551 - closed) • Sahil Sharma • 18.7
• Ensure stages mini graph works with GraphQL res... (#581322 - closed) • Sahil Sharma • 18.7

What does this MR do and why?

This MR removes the deprecated formatPipelinesGraphQLDataToREST utility method and migrates the merge request pipelines table to use native GraphQL data structures.

Key changes:

• Removes data transformation layer: Eliminates formatPipelinesGraphQLDataToREST method that was converting GraphQL responses to REST format
• Uses pipeline_details fragment: Adopts the shared GraphQL fragment which provides all necessary pipeline properties including:
  • hasManualActions
  • hasScheduledActions
  • stages
  • Merge request metadata (added sourceBranch field)
• Updates property access: Modifies components to handle both GraphQL and REST property names during the transition period
• Improves error handling: Enhances pipeline action error handling with specific error messages and Sentry logging

What's not included:

Currently this MR does not display downstream pipeline jobs, which is a known bug and will be handled separately.

How to set up and validate locally

1. Update any project's .gitlab-ci.yml to include manual & scheduled jobs with multiple stages.

Example yaml:

workflow:
  rules:
    - if: $CI_PIPELINE_SOURCE == "merge_request_event"
    - if: $CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH

stages:
  - build
  - test
  - deploy
  - cleanup

# Build stage - runs automatically and creates artifacts
build_app:
  stage: build
  script:
    - echo "Building application..."
    - mkdir -p build
    - echo "Build output $(date)" > build/app.txt
    - echo "Version 1.0.0" > build/version.txt
  artifacts:
    paths:
      - build/
    expire_in: 1 week
  rules:
    - if: $CI_PIPELINE_SOURCE == "merge_request_event"
    - if: $CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH

# Test stage - runs automatically with artifacts from build
test_unit:
  stage: test
  script:
    - echo "Running unit tests..."
    - cat build/app.txt
    - echo "Tests passed!"
  artifacts:
    paths:
      - build/
    reports:
      junit: build/test-results.xml
    expire_in: 1 day
  dependencies:
    - build_app
  rules:
    - if: $CI_PIPELINE_SOURCE == "merge_request_event"
    - if: $CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH

# Manual test job - requires manual trigger
test_integration:
  stage: test
  script:
    - echo "Running integration tests..."
    - cat build/version.txt
    - echo "Integration tests completed"
  when: manual
  dependencies:
    - build_app
  rules:
    - if: $CI_PIPELINE_SOURCE == "merge_request_event"
    - if: $CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH

# Deploy to staging - manual trigger
deploy_staging:
  stage: deploy
  script:
    - echo "Deploying to staging environment..."
    - cat build/app.txt
    - echo "Deployment complete"
  artifacts:
    paths:
      - build/
    name: "staging-deployment-$CI_COMMIT_SHORT_SHA"
    expire_in: 3 days
  when: manual
  dependencies:
    - build_app
  rules:
    - if: $CI_PIPELINE_SOURCE == "merge_request_event"

# Deploy to production - manual trigger (only on default branch)
deploy_production:
  stage: deploy
  script:
    - echo "Deploying to production environment..."
    - cat build/app.txt
    - echo "Production deployment complete"
  when: manual
  allow_failure: false
  dependencies:
    - build_app
  rules:
    - if: $CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH

# Scheduled job - only runs on schedules
nightly_cleanup:
  stage: cleanup
  script:
    - echo "Running nightly cleanup..."
    - echo "Cleanup completed at $(date)"
  rules:
    - if: $CI_PIPELINE_SOURCE == "schedule"

# Manual cleanup job
manual_cleanup:
  stage: cleanup
  script:
    - echo "Running manual cleanup..."
    - echo "Manual cleanup completed"
  when: manual
  allow_failure: true
  rules:
    - if: $CI_PIPELINE_SOURCE == "merge_request_event"
    - if: $CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH

2. Enable Feature.enable(:mr_pipelines_graphql) feature flag
3. Navigate to a merge request in this project with pipelines
4. Verify the pipelines table displays correctly with:
   • Pipeline stages and jobs
   • Manual action buttons (if applicable)
   • Scheduled action buttons (if applicable)
5. Test pipeline actions (cancel/retry/run manual jobs/download artifacts) work as expected
6. Verify no console errors
