Review library-bulk-update PRs

These PRs are created by the scheduled compatibility workflow and are expected to update supported library versions by changing metadata/**/index.json. They may also refresh the generated root COVERAGE.md when tested-version changes affect the coverage table.

Historical Review Logic

Previous reviews follow a simple pattern:

  • Approve silently when the PR only updates the expected metadata index files, optionally with generated root COVERAGE.md, and CI is green, then enable auto-merge.
  • Close the PR when it contains unrelated changes such as workflow files, Gradle files, generated sources, or test code that clearly did not belong in a bulk version update.
  • Close stale PRs with merge conflicts instead of repairing them manually if a newer bulk-update PR will supersede them.
  • If CI looks flaky or inconsistent with the diff, ask for or trigger a rerun rather than approving blindly.
  • Treat generated-source changes as suspicious in this PR type. They should normally not appear here.

Workflow

  1. Inspect the PR summary.

    • Confirm the PR has label library-bulk-update.
    • Read the body and verify it is a bot-generated "Added tested versions" summary.
    • Gather files, reviews, issue comments, inline comments, and status checks.

  2. Validate the diff scope first.

    • Expected files: metadata/<group>/<artifact>/index.json, plus the generated root COVERAGE.md when the PR updates tested versions.
    • Normal change shape: new values appended to tested-versions, with formatting-only line movement around the surrounding JSON.
    • Be suspicious of changes to latest, metadata-version, test-version, allowed-packages, requires, or URL fields unless the PR clearly needs them.
    • A pure pre-release-to-release promotion produced by addTestedVersion is allowed when it is limited to the matching library and consists only of:
      • metadata/<group>/<artifact>/<oldVersion> -> <newVersion>
      • tests/src/<group>/<artifact>/<oldVersion> -> <newVersion>
      • stats/<group>/<artifact>/<oldVersion> -> <newVersion>
      • matching index.json changes to metadata-version, tested-versions, and exact-version artifact URLs
    • Reject or close the PR if it changes:
      • .github/workflows/**
      • ci.json
      • gradle/**, build.gradle, settings.gradle, gradle.properties
      • tests/src/** outside a pure matching pre-release promotion rename
      • stats/** outside a pure matching pre-release promotion rename
      • generated Java sources
      • any other non-metadata/**/index.json file, except the generated root COVERAGE.md

  3. Check that the PR body matches the diff.

    • Every library listed in the body should correspond to an index.json diff.
    • Added tested versions should match the actual JSON changes.
    • A COVERAGE.md refresh is allowed as generated fallout from the listed library updates; it does not need to be listed as a separate library change.
    • There should not be hidden updates outside the listed libraries, except the generated root COVERAGE.md.

  4. Check CI before deciding.

    • Required baseline: JSON validation, metadata tests, and style checks must be green.
    • If the PR unexpectedly triggered build-logic or workflow-heavy jobs, that is a sign the diff scope is wrong. A root COVERAGE.md change alone is not workflow-heavy.
    • If checks failed because the PR is contaminated by unrelated changes, close it.
    • If checks failed due to likely infra flakiness or a suspicious runner issue, request a rerun or rerun all relevant tests before approval.

  5. Review each changed index.json.

    • Confirm the new versions were added under the correct metadata-version entry.
    • Preserve existing ordering conventions; new tested versions are typically appended in version order.
    • Do not accept dropped tested versions, entry reshuffling, or unrelated field edits without a clear reason.
    • For pre-release promotions, confirm metadata-version moved from the matching pre-release to the corresponding full release, old pre-release values were removed from tested-versions, and any test-version references were updated only when they pointed at the promoted test directory.

  6. Apply URL verification when URL fields changed.

    • This is higher scrutiny than a normal bulk-update PR.
    • Review source-code-url, test-code-url, documentation-url, and repository-url with the same rules used by PopulateArtifactURLs.
    • For pre-release promotions, verify the source-code-url, test-code-url, and documentation-url values were rendered from the old version to the promoted metadata-version or otherwise corrected to an exact-version URL. Do not accept stale URLs that still point at the old pre-release.

  7. If the PR is clean and approved, enable auto-merge.

    • In this repository, approved automation PRs are expected to auto-merge after approval.
    • Do this after the approval is submitted, and only when the PR is otherwise mergeable.

URL Verification Rules

If any URL field changed, verify all of the following:

  • repository-url is the canonical repository root URL.
  • repository-url must not include a versioned tree path such as /tree/<tag>.
  • source-code-url, test-code-url, and documentation-url must point to the exact library version in the changed entry.
  • Do not accept unversioned docs, latest, current, or branch-based docs unless there is no versioned source and the PR clearly justifies it.
  • Prefer Maven -sources.jar, -test-sources.jar, and -javadoc.jar when they exist and are valid.
  • If a Maven -sources.jar or -test-sources.jar is used, verify it contains real source files such as .java, .kt, .scala, or .groovy, not only metadata or license files.
  • If the URL points to a repository tree or archive instead of Maven, verify that it resolves to real source or test files for the exact version tag.
  • If a candidate source or test URL cannot be verified with confidence, it should not be approved as-is.
  • For pre-release promotions, template rendering is expected: old-version URL tokens may be replaced by the promoted version only when the rendered URL resolves and archive/source checks pass.

Use the logic from tests/tck-build-logic/src/main/groovy/org/graalvm/internal/tck/harness/tasks/PopulateArtifactURLs.java, especially the urlUpdateInstructions and sourceArtifactVerificationInstructions rules.

Decision Rules

Approve when all of these are true:

  • The PR is limited to the expected metadata/**/index.json files, optionally with generated root COVERAGE.md.
  • Or the PR is a pure verified pre-release promotion rename limited to the matching metadata/, tests/src/, stats/, index.json, and optional root COVERAGE.md changes.
  • The diff is only tested-version maintenance or clearly justified URL maintenance.
  • CI is green, or any rerun confirms green status.
  • Any changed URLs were verified against the exact version.
  • Auto-merge was enabled after approval when the PR is mergeable.

Close or reject when any of these are true:

  • The PR contains unrelated files or generated code.
  • The PR is stale, conflicted, or clearly superseded by a newer automation run.
  • CI failures point to a real regression or invalid update.
  • URL changes cannot be verified confidently.

Ask for rerun or deeper investigation when:

  • The diff looks correct but CI failed in a way that smells like infrastructure noise.
  • A generated file changed and you need to confirm whether the workflow accidentally regenerated something.

Output Style

Match the historical style:

  • Clean PR: approve with no comment or a very short confirmation, then enable auto-merge.
  • Contaminated PR: leave a short factual comment explaining why it is being closed or should not be merged.
  • Flaky CI: leave a short comment requesting or noting a rerun.
