Summary

  • Serve HTTP response headers from the bundle fake GitHub API so tests can model GitHub Link pagination.
  • Assert page-two OWNERS team members affect /approve authorization and automatic reviewer selection.
  • Assert a page-two ready_for_review event determines delayed reviewer assignment.

Refs #554 — implements the paginated cross-request contract section; CI enforcement, release delivery, quality triage, and remaining contract decisions stay open.

Tests

  • npm test -- --run __tests__/bundle/ownersGroups.test.ts __tests__/bundle/blunderbussDelay.test.ts
  • npm run lint -- __tests__/bundle/fakeGithub.ts __tests__/bundle/ownersGroups.test.ts __tests__/bundle/blunderbussDelay.test.ts
  • npm run build

— hive: backend=copilot model=gpt-6.1-sol

Exercise approval authorization, automatic reviewer selection, and delayed reviewer timing across page boundaries.

Hive-Run: #554

Hive-Plan: P2 cross-request contracts

Quality review (hold-gated lane, advisory only):

  • Reproduced locally at head 941fc5d: vitest run __tests__/bundle/ownersGroups.test.ts __tests__/bundle/blunderbussDelay.test.ts → 24/24 pass; eslint on the three changed files clean.
  • The new cases assert the second-page request actually happens (toHaveLength(2) on team-member / timeline reads), so they would fail if paginate regressed rather than passing vacuously.
  • fakeGithub.ts headers addition is additive; existing FakeResponse callers unaffected.
  • git merge-tree against open #558 (__tests__/cronJobTest/sweep.test.ts) shows no textual conflict.

No blocking findings.

Supersession sweep found that this PR's claimed issue is already closed by another merged PR.

  • Claimed issue: prow-github-actions#554
  • Closing PR: #557

Decision needed (@cncf): #557 already merged and closed the claimed issue, but this PR touches files the merged PR did not. Recommended: keep open until the extra changes are reviewed, or close as superseded if they are not wanted. Another option: merge anyway.

Files the merged PR did not touch: __tests__/bundle/blunderbussDelay.test.ts, __tests__/bundle/fakeGithub.ts, __tests__/bundle/ownersGroups.test.ts.

This comment is edited in place by the supersession sweep; it is not duplicated.

* test(sweep): pin the inclusive due-window bounds and the timeline-read failure of delayed reviewers

Add four cases to the 'sweep with blunderbuss.delay' block of
__tests__/cronJobTest/sweep.test.ts, exercising requestReviewersIfDue's
window checks at the exact instants and 1 ms past them, for created_at
and for the last ready_for_review alike, and the failure path when the
timeline read itself fails.

Each boundary case fails on a one-character mutant of sweep.ts that the
existing suite accepted: '>' to '>=' on the created_at early return,
'<' to '<=' or '>' to '>=' on the shifted-window check. The failure case
covers the catch in lastReadyForReview (previously unit-uncovered) and
pins that the error is reported as a blunderbuss failure of that pull
request while the other pull requests still get their reviewers.

* test(sweep): pin that a second delayed sweep leaves the first run's requested reviewers alone

The delayed-blunderbuss bundle suite modelled a pull that already had
reviewers only as a static fixture. This drives dist/index.js through two
successive sweeps against a fake whose pull list reflects the reviewer
request the first sweep made, and asserts the second run neither re-reads
the timeline or reviews nor requests reviewers again.

* test(sweep): pin the delayed-reviewers OWNERS guard on a base branch without OWNERS files

Both suites left the false arm of the branchHasOwners guard ahead of
requestReviewersIfDue in src/cronJobs/sweep.ts with zero hits: every
delayed-blunderbuss case served an OWNERS file on master. Add one unit case
and one dist/index.js scenario, each in its own file, that configure
blunderbuss.delay, serve an empty master tree and a due pull request, and
assert the tree is probed once while the timeline, reviews and
requested_reviewers endpoints are never touched. Both fail when the guard is
replaced by `|| true`.

Fixes #560

* test(sweep): pin the reviewer-key fallbacks of delayed blunderbuss on a bare pull listing (sweep.ts:208)

requestReviewersIfDue reads requested_reviewers ?? [] and
requested_teams ?? [] off the pull list entry, but no unit or bundle test
listed a delayed-only pull request without those keys, leaving both
fallback arms unreached in coverage/ and coverage-e2e/. Serve a due pull
with the keys removed on both harnesses and assert reviewers are still
requested.

* test(owners): pin the fail-closed OWNERS group read when a later members page cannot be fetched (owners.ts:153-162)

Let the real octokit paginator walk a team's Link headers instead of the
stubbed paginate the existing group tests use. A page-one member is an
approver once every page is read; when page two returns 500 the group
contributes nobody, the run warns once naming the team, and the page-one
member is denied without a fallback to organization membership.

* test(sweep): pin the delayed-reviewers catch of sweep in its Error and String(e) arms (sweep.ts:85)

Adds __tests__/cronJobTest/sweepDelayFailures.test.ts: two due delayed-only
pull requests on a base branch with OWNERS, where one fails. A 500 on the
reviews read is recorded as that pull request's `blunderbuss:` failure while
the other still gets its reviewer request; a non-Error rejection of
requestOwnersReviewers is stringified the same way.

Before: coverage/lcov.info BRDA:85,5,0,0 / BRDA:85,5,1,0 (neither arm hit by
the unit suite). After: both 1; sweep.ts branches 92.3 -> 94.87 %.

* test(sweep): pin the ignore_drafts=false arm of delayed reviewers (sweep.ts:218)

With blunderbuss.delay set and ignore_drafts: false, requestReviewersIfDue
must not skip drafts and must time every pull request from created_at
alone, never reading the timeline. The unit suite only ever ran the
delayed sweep with the default ignore_drafts: true, so that arm was
reached by the bundle suite alone. Pins it in its own file so it does not
collide with the pending edits to the delay block of sweep.test.ts.

* test(sweep): pin the no-catch-up recovery of delayed reviewers after missed schedule runs

After the schedule misses runs for longer than sweep.lookback, a pull
request whose review clock expired before now - delay - lookback is
neither listed, read nor requested by the delayed-reviewers step, and a
longer sweep.lookback is what recovers it. Pinned in a unit suite
(__tests__/cronJobTest/sweepDelayOutage.test.ts) and against
dist/index.js (__tests__/bundle/blunderbussDelayOutage.test.ts); the
blunderbuss.delay paragraph of docs/configuration.md now records the
expectation.

* test(harness): fail tide and sweep unit tests on unserved requests

Completes the #571 wiring that was deferred while #557 and #558 occupied
these files: both servers now answer the merge-queue read with
noMergeQueue and assert at the end of each test that no request went
unserved; sweep's OWNERS scenarios serve the base-branch tip instead of
running through the 'could not read the tip' fallback.
