Poll an Attested Head's Checks in pr_review.py wait by ptr727 · Pull Request #2722 · ptr727/ProjectTemplate

ptr727 · 2026-10-10T10:24:38Z

Summary

On a pull request into a branch other than the default, a fix push covered by an attested local pass took the held branch of pr_review.py wait. That branch returned exit 0 at once with no status= line while checks were still running, which a caller reading only the exit code took as ready.

The held branch now polls the head's checks (the full query, since the liveness query carries none) while held_checks_open reads that they can still move the merge:

Q_FULL reads each rollup member's isRequired(pullRequestNumber:) and the pull request's state. A missing key reads as required or open.
The poll ends once the merge reads CLEAN, UNSTABLE, or HAS_HOOKS, or the pull request is no longer open. A BLOCKED merge carrying a stuck required check ends it too, its 44 already decided.
It holds on a required check still settling (one running long included), on any settling check while no required one has posted (a required aggregator behind needs: enters the rollup only once its dependencies finish), on an empty readable rollup under BLOCKED, BEHIND, or DRAFT, and on a merge still UNKNOWN. An unrecognized review shape ends it, its 43 already decided.
checks_settling is the complement of checks_stuck, leaving the state taxonomy to check_shape.

A covered head still open at the timeout exits 30 with status=CHECKS_PENDING, ranked ahead of the 44 arm. The poll stops at once where the head is no longer covered: a push exits 49, and a requested round exits 30 with status=PENDING unless a 46 or 47 quota reading outranks it. The wait help text and scripts/README.md state the new readings. The Copilot (non-held) path is unchanged.

Closes on promotion: #2685

Remaining Local-Review Findings

Each finding still open after the local passes, with its class and outcome:

introduced, design: the held poll loop is a second inline copy of the Copilot loop's backoff shape. Deferred to Share One Bounded Backoff Loop Between pr_review.py wait's Two Polls #2723.
introduced: the 44 arm still fires on any stuck check under BLOCKED, and its README and code-comment rationale cites a ruleset read this change now makes for free. Deferred to Narrow pr_review.py wait's Exit 44 to Required Checks Read From isRequired #2724.
introduced: the seconds-long gap after a needs: dependency finishes, or before a slower workflow's jobs register, can end the poll early if a read lands in it. Every fleet ruleset measured requires a single aggregator, and the measured gap is one to three seconds against a poll interval of fifteen or more.
introduced: a BEHIND merge with a failed required check ends the poll with exit 0, since the 44 arm requires BLOCKED. That arm's scope is Narrow pr_review.py wait's Exit 44 to Required Checks Read From isRequired #2724's.
introduced: the held poll reads the full Q_FULL document each iteration where a narrower one would do. Deferred to Share One Bounded Backoff Loop Between pr_review.py wait's Two Polls #2723.
introduced: scripts/README.md's 30 paragraph does not name the immediate 44 a stuck required check gives, and check_nodes's docstring does not name the required key. Deferred to State the Held Poll's Immediate 44 in scripts/README.md and check_nodes's Node Keys #2725.

Summary by CodeRabbit

Bug Fixes
- The wait command now continues polling checks that could affect a held pull request, even when a local pass has been attested.
- If checks remain unsettled at timeout, wait reports CHECKS_PENDING with exit code 30. Closed pull requests and terminal merge states end polling.
- Long-running checks are no longer treated as stuck. Exit code 44 is reserved for stuck required checks when the merge state is BLOCKED.
Documentation
- Clarified polling outcomes and the distinction between pending checks, pending reviews, and other results.

On a pull request into a branch other than the default, a fix push covered by an attested local pass took the held branch of `wait`, which returned exit 0 at once with no status line while checks still ran. `wait` now polls the head's checks on that branch until none is still settling, a stuck shape ending the poll as before, and a check not concluded by the timeout exits 30 with `status=CHECKS_PENDING`. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

The held poll now stops once the merge reads CLEAN, UNSTABLE, or HAS_HOOKS, so a check no ruleset requires does not hold it, and keeps polling through the pickup grace on an empty rollup, which is a push whose check suites have not registered yet. The exit 0 help text names the rollup window it reads, and a test pins that an unattested held head exits 49 without polling its checks. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

The help text, the held note, and the CHECKS_PENDING line now name the CLEAN, UNSTABLE, or HAS_HOOKS exit and bound the empty-rollup hold to the pickup grace. Tests pin the HAS_HOOKS member, the unreadable-node exclusion, and a review requested during a held wait ending the poll. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

📝 Walkthrough

Walkthrough

The wait command now polls checks on attested held pull-request heads when those checks can affect merge state. It distinguishes required and optional checks, uses check and pull-request state to determine whether polling continues, and reports CHECKS_PENDING with exit code 30 at timeout. Documentation and tests cover the updated outcomes.

Changes

Held-head check polling

Layer / File(s)	Summary
Required-check data `scripts/pr_review.py`, `tests/test_pr_review.py`	The full query reads pull-request state and required-check flags for both check node types. Normalized check entries preserve the required flag, and tests verify the query and normalized values.
Held-head check state `scripts/pr_review.py`, `tests/test_pr_review.py`	New helpers identify checks that are still settling and determine whether check and merge state keep a held head open. Tests cover check-state classifications and held-head conditions.
Wait polling and outcomes `scripts/pr_review.py`, `scripts/README.md`, `tests/test_pr_review.py`	The wait command polls checks on attested held heads and reports `CHECKS_PENDING` with exit code 30 when checks remain open at timeout. Documentation and tests cover terminal states, exit-code precedence, and head changes.

Priority: ⬇️ Low

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 3f9f6

When a merge is blocked for another reason, a stuck optional check can make wait report exit 44 instead of the documented outcome. The impact is minor and the fix is small, so the change is otherwise mergeable.

A BLOCKED merge carrying a stuck check already has its exit, so a failed lint job no longer waits out a slow test job before the held poll returns 44. The README's wait contract now names the held-head check poll and status=CHECKS_PENDING, and the held_checks_open docstring rewraps at the column the rest of it keeps.

The full query now reads each rollup member's isRequired for this pull request. A held poll holds on a required check still settling, or on any check while no required one has posted, since a required aggregator behind needs enters the rollup only once its dependencies finish. Only a stuck required check ends the poll early on a BLOCKED merge, so an optional failure no longer returns 44 while the gate still runs, and an optional straggler no longer holds a merge BLOCKED on a thread. The help text, the CHECKS_PENDING line, and scripts/README.md name --check-grace rather than the ignored pickup grace, state the PENDING exit a round requested mid-poll gives, and split the sentences the sentence-length check flagged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A covered head whose required check still runs at the timeout now exits 30 ahead of the 44 a stuck optional check would give, the reading the poll itself uses. An empty rollup holds the poll for as long as the merge reads BLOCKED or UNKNOWN rather than for the check grace alone, so a lagging pull_request event no longer ends it in a silent 0, and a conflicted pull request, which runs no workflow, is not held. The settling predicate now leaves the state taxonomy to check_shape. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A recorded local strict-review pass covers head 7a44d208be4aa88bd569a1f48823b22796415d05, the content this pull request carries at that commit against develop, and it recorded 7 findings.

GitHub recomputes mergeStateStatus after a check concludes and reads UNKNOWN meanwhile, so a held poll ending on that read returned 0 over a failed required check. The poll now holds while the merge reads UNKNOWN, and CHECKS_PENDING names that case. Tests pin a push and a review request landing mid-poll, and the empty-rollup test's name says it holds UNKNOWN too. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

GitHub reads mergeStateStatus UNKNOWN on a merged or closed pull request for good, so the UNKNOWN hold kept a wait on one polling to its timeout. Q_FULL now reads the pull request's state, and the held poll ends once it is no longer open. The help text, the held note, and scripts/README.md now state the poll's end conditions as the code has them. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A recorded local strict-review pass covers head f6f6a0ede156ccbb8d9406f1e1f77ac238bf1b48, the content this pull request carries at that commit against develop, and it recorded 1 finding.

A round requested during the held poll ends it with status=PENDING only where no quota signal is on record, since the 46 and 47 arms rank ahead of it. The help text and scripts/README.md now say so, and a test pins that ordering. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Only required checks hold the held poll, and a stuck one exits 44 rather than 30, so the help text and scripts/README.md now say a held exit 0 has its required checks settled and a held 30 has one still settling. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

An unrecognized review shape exits 43 ahead of every check reading, so the held poll now stops on one rather than polling to the same code. The help text and scripts/README.md state the poll as running only while the checks can still move the merge, without a partial list of its end conditions, and the README names wait as the subject of the failure-mode sentence the new text separated from it.

A recorded local strict-review pass covers head e64ffc848070392d8449f830919b7b6e25da63bf, the content this pull request carries at that commit against develop, and it recorded 2 findings.

RUNNING_LONG is the weaker stuck reading, since duration alone cannot tell a stalled job from a slow one, so a held poll now keeps waiting on it rather than ending at the stall threshold and exiting 44 over a job that would finish green. At the timeout it exits 30 like any other settling required check. scripts/README.md again says an attested head whose checks settle ends as covered. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A rollup read off a commit other than the head is empty here, which no wait clears, so the held poll's empty-rollup hold now skips it. The exit 0 help text and scripts/README.md name the closed pull request case, and the README says coverage lands before CI concludes rather than before it starts.

A recorded local strict-review pass covers head d7c89d7277e29c21a20abae9ae1617f4f0974ed8, the content this pull request carries at that commit against develop, and it recorded 1 finding.

An attested head can carry an answer outside a review, and a round requested during its poll then exits 40 rather than PENDING. The help text and scripts/README.md now name that reading with the quota ones, and a test pins the ordering. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

pull_request workflows run on a draft and on a branch behind its base, so an empty rollup there is a push whose suites have not registered, as on a BLOCKED merge. Only a conflicted pull request, which runs no workflow, is not held. The 47 help text now names the held head's 30 and 44 among the codes that outrank it.

A recorded local strict-review pass covers head 33457a29410377b2620c6bb8d6b03e8c2e26fbe1, the content this pull request carries at that commit against develop, and it recorded 3 findings.

The exit 44 help text now says a held head polls a running check only while it can still move the merge, the README's 30 paragraph names the CLEAN, UNSTABLE, or HAS_HOOKS shortcut that ends the poll first, and the Q_FULL comment no longer claims the query runs once per transition, since the held poll reads it every iteration. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A test now asserts Q_FULL selects isRequired on both rollup shapes and the pull request's state, since a dropped field reads as required or open and holds a held wait to its timeout, and another reads a status context's own required flag. The 44 help text and the README's 30 paragraph say a required check running long on a held head is still polled. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Outcomes for the findings this pull request's body lists under "Remaining Local-Review Findings" (6), none of which opened a thread:

The held poll loop duplicating the Copilot loop's backoff shape: Deferred to Share One Bounded Backoff Loop Between pr_review.py wait's Two Polls #2723.
The 44 arm firing on any stuck check under BLOCKED, and its README and code-comment rationale: Deferred to Narrow pr_review.py wait's Exit 44 to Required Checks Read From isRequired #2724.
The seconds-long registration gap after a needs: dependency finishes, or before a slower workflow's jobs register: No change needed. Every fleet ruleset measured requires the single aggregator, the gap measured one to three seconds, and the poll interval is fifteen seconds or more, so a read landing in it is rare and costs an early 0 the next wait corrects.
A BEHIND merge with a failed required check ending the poll with 0: Deferred to Narrow pr_review.py wait's Exit 44 to Required Checks Read From isRequired #2724, which owns the 44 arm's merge-state condition.
The held poll reading the full Q_FULL document each iteration: Deferred to Share One Bounded Backoff Loop Between pr_review.py wait's Two Polls #2723 (scope added in a comment there).
The README's 30 paragraph not naming the immediate 44, and check_nodes's docstring not naming the required key: Deferred to State the Held Poll's Immediate 44 in scripts/README.md and check_nodes's Node Keys #2725.
