chore(ci): enforce issue dependencies with a blocked label and a pull-request check - #1035
Merged
Merged
Conversation
…ired PR check A dependency between issues was recorded only in prose, so nothing kept a contributor from claiming or opening a pull request for work whose prerequisite was still open, and nothing said when it opened up. - tools/issue_dependencies.py derives the `blocked` label from GitHub's native "Blocked by" links. A blocker is resolved only when it is closed as completed; one closed as not planned or as a duplicate keeps the dependent blocked and flags it `needs-triage` with one notice. Removing the label posts one comment and re-runs the failed check of the open pull requests that link the issue. - .github/workflows/issue-dependencies.yml runs it when an issue is closed or reopened, hourly (GitHub sends no event for link edits) and on demand. - .github/workflows/pr-dependencies.yml adds the "Issue dependencies" check: it fails while a linked issue (Fixes / Closes / Resolves / Refs) is blocked, unless the pull request closes every open blocker too or a maintainer sets `dependency-override`. It runs the base commit's copy of the script, never the pull request's, with a read-only token. - /assign refuses a blocked issue (the label, or an open blocker GitHub still counts, so the hourly lag leaves no gap). - CONTRIBUTING gains "Dependencies between issues"; CLAUDE.md, AGENTS.md, the PR template and the CHANGELOG describe the rule. Fixes #1034 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Reviewer's GuideThis PR turns GitHub’s native Blocked by relationships into an enforced workflow: a tested reconciliation script maintains derived labels and triage notices, /assign and documentation respect dependency state, and a read-only base-commit PR workflow blocks work on unresolved dependencies with an explicit override or same-PR blocker closure.

**Blocked work bypasses the required check**
When a pull request changes `.github/workflows/pr-dependencies.yml` while preserving the required check name, gitHub evaluates the pull request’s workflow definition, so the PR can skip or replace the dependency check even though the script is checked out from the base commit. Branch protection then accepts blocked work.
Run the required check from a workflow definition that pull requests cannot modify.

**Contributors bypass the dependency gate**
When a non-maintainer who can label pull requests applies `dependency-override`, `check_pull_request` treats the label as sufficient authorization and passes the PR without checking who applied it, so the contributor can bypass the dependency gate.
Verify that a maintainer authorized the override before allowing the check to pass.

**Blocked pull requests keep a green check**
When a linked issue gains an unresolved blocker after its pull request’s dependency check has passed, `run_sync` adds the `blocked` label but schedules reruns only for unblocked issues. The pull request keeps its passing required check and can merge while the issue is blocked.
Re-run dependency checks for pull requests linked to issues that become blocked.

**Assignment ignores incomplete blockers**
When a blocker is already closed as not planned or duplicate and `/assign` runs before the next sync, `fetch_issue` uses only the open-blocker count, so `decide` sees no blocker and allows the assignment while the `blocked` label has not caught up. The issue is assigned even though policy still considers it blocked.
Have `/assign` detect blockers closed as not planned or duplicate, rather than relying only on the open-blocker count and label.

</code_context>
<issue_to_address>
**Stale blocked labels remain**
When an issue has more than 50 labels and a relevant label is outside the first 50 returned by GitHub, the labels query returns only the first 50 labels, so `plan_issue` misses `blocked` and does not remove it from an unblocked issue. It can also miss `dependency-override` during a PR check. The stale label makes `/assign` refuse the issue.
Fetch all labels before using them to plan sync changes or evaluate dependency overrides.

+
+_GH_TIMEOUT_SECONDS = 60
</code_context>
<issue_to_address>
**Cross-repository blockers are confused**
When not-completed blockers in different repositories share an issue number, `not_completed_notice` and `CANCELLED_MARKER` identify blockers only by number. The notice points maintainers to the wrong repository, and `_already_noticed` treats one blocker’s notice as the other’s, suppressing its re-planning request.
Include the blocker’s repository as well as its number in both the notice and its deduplication marker.

</code_context>
<issue_to_address>
**Blocked issue gets assigned**
When a blocker is added or reopened after `/assign`'s final issue read but before its assignment POST, `_perform` fetches the issue's blocker state, then posts the assignment after its final read. If a maintainer adds or reopens a blocker between that read and the POST, the assignment lands on a blocked issue and remains there; the next sync updates the label but does not undo the assignment.
After assigning, fetch the dependency state again and release the new claim if an open blocker appeared.

+ blocked = sum(1 for i in issues if i.is_open and is_blocked(i.blockers))
+ unblocked: set[int] = set()
</code_context>
<issue_to_address>
**Reopened blocker gets unblocked notice**
When a blocker is reopened after `run_sync` reads the dependent but before it applies the removal plan, `run_sync` plans from a snapshot, then applies the label removal without rechecking the blocker. If the blocker is reopened after the snapshot, the dependent loses `blocked` and receives an unblocked notice even though it is waiting again; the later reconciliation restores the label but cannot retract the notice.
Re-read the dependent's blocker state immediately before removing `blocked` and posting the unblocked notice.

<issue_to_address>
**In-progress check stays failed**
When a PR check reads an open blocker, the blocker closes, and sync checks that PR before the check finishes, the sync sees the PR's dependency check as still running, so it does not re-run it; that check can then finish with a failure based on its earlier blocker read. Later syncs see the issue already unblocked and do not retry, leaving the required check failed until another PR event.
Recheck the dependency check after in-progress runs finish, or retry failed checks independently of the label-removal transition.

+ if issue.is_open:
+ unblocked.add(issue.number)
</code_context>
<issue_to_address>
**Failed sync loses unblocking work**
When the `blocked` label deletion succeeds but the comment POST or a later sync write fails, `run_sync` exits after deleting the label, before reliably posting the notice and rerunning linked PR checks. The next reconciliation sees no label transition to retry, so the notice is missed and linked PRs can keep stale failed checks.
Make the notice and PR-check rerun recoverable even when a later sync write fails after the label is deleted.
Also at `tools/issue_dependencies.py:496`, `tools/issue_dependencies.py:507`.

+ marker = CANCELLED_MARKER.format(blocker=b.number)
</code_context>
<issue_to_address>
**Unblocking without a label is silent**
When a PR check fails while a blocker is open, but the blocker closes before sync has applied `blocked` to the issue, `plan_issue` returns no change when an issue has no `blocked` label and no unresolved blockers, and `run_sync` only adds issues to `unblocked` after removing that label. A failed PR check then is not re-run; the same ordering also loses the unblocked comment if the label was never synced.
Identify newly unblocked issues from dependency-state changes rather than requiring a prior label removal, and ensure their notices and failed checks are retried if a write fails.

**Later pull requests are skipped**
When the repository has more than 300 open pull requests and a later one links an issue just unblocked by the sync, `_rerun_pr_checks` stops after three pages without checking for more results. The later pull request keeps its failed dependency check, and a subsequent sync does not revisit it.
Continue paginating open pull requests until there are no more results.

<issue_to_address>
**Malformed close syntax bypasses check**
When a PR uses a close keyword without the whitespace GitHub requires before the issue reference, when a PR uses `Fixes#12` for an open blocker, `linked_issues` counts #12 as closed even though GitHub does not close it. `check_pull_request` then skips that blocker and lets the PR pass while the blocker remains open.
Only count references as closing when they match GitHub's actual closing-keyword syntax; treat malformed forms as references at most, never as closes.

**Failed reruns go untested**
When the pull-request listing succeeds but the rerun POST fails, `test_a_failing_rerun_is_not_a_failed_sync` raises on `_rerun_pr_checks`' first GET of the pull-request list, before the `rerun-failed-jobs` POST; its warning assertion still passes if a POST failure is handled incorrectly.
Let the pull-request listing succeed and configure the fake to fail specifically on the `rerun-failed-jobs` POST.

- Run the "Issue dependencies" check on pull_request_target, so the workflow and the script come from the default branch and a pull request cannot rewrite the check that judges it. Nothing from the pull request is checked out or run, and the token stays read-only. - Count a blocker as closed by the pull request only in the form GitHub closes on merge (`Fixes #N`, one keyword per issue); `Fixes#N`, `Fixes: #N`, a URL or the second issue of a list no longer exempt it. - Honour `dependency-override` only when a maintainer added it last, checked against the issue events. - Reconcile pull-request checks by state on every sync: re-run the check of any open pull request whose last result no longer matches its linked issues, in both directions, across every page of pull requests. A check still running or a failed re-run is picked up by the next run. - Re-read an issue right before unblocking it, post the notice before removing the label and make it idempotent with a marker, so a reopened blocker or a half-finished run never yields a wrong or lost notice. - Key not-completed notices by owner/repo#N; check that labels fit in one page; read pull-request descriptions in linear time (line walker for fences, str.find for HTML comments; regex.md rule 6). - /assign also refuses an issue whose blocker was closed without being completed before the label caught up. - CONTRIBUTING says the check is not yet required until branch protection lists it, and no notice is promised that may not come.

A code span delimited by two or more backticks (``Fixes #1``) was read as two empty single-backtick spans, so the reference inside stayed in the prose and counted as closing: a blocker GitHub would not close was exempted. Code spans are now paired as CommonMark pairs them, a run of N backticks up to the next run of exactly N, within one paragraph so that a stray backtick cannot hide the links in the paragraphs after it. Linear, like the rest of the reader; regression and linear-time cases added. Refs #1034 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Fixes #5\n\n Fixes #1starts a genuine indented code block. The current parser keeps it, adds#1toclosing, andcheck_pull_requestskips the open blocker even though GitHub does not process code-block text as a closing reference.Strip indented lines only at the start of a block or after a blank line. Continue stripping the block, but preserve four-space lines that follow nonblank paragraph text.

A reference inside an indented code block (`Fixes #5\n\n Fixes #1`) was counted as closing, so a blocker GitHub would not close was exempted. Closing references are now read without indented code blocks: a line indented four spaces or a tab opens one only at the start, after a blank line or after a heading, never as a paragraph continuation, and the block runs through indented and blank lines (linear line walker). Links are still read with those lines kept. Inside a list item, a line indented four spaces after a blank line is prose, so dropping it from the links could hide a linked blocked issue; dropping it from the closing references can only refuse an exemption.

Keeping indented references in the linked-issue set avoids hiding blocked issues in list-item prose. Removing them only from closing references can refuse an exemption, but cannot grant an invalid exemption. The parser also preserves four-space paragraph continuations. The tests cover the cases you listed. I did not run them. ✏️ Learnings added

An indented line right after a closed fence, a setext underline or a thematic break opens an indented code block in CommonMark, but the reader treated it as a paragraph continuation, so a reference in it counted as closing and exempted an open blocker. - Fenced-code lines are kept as blank placeholders instead of being dropped, so the boundary the fence made survives for the later readers. - _ends_block() adds exact setext-underline and thematic-break forms to the ATX heading check; a line such as `-_-` or `**` stays paragraph text. - Regression and linear-time cases added.

…ailures Closing references: - A blocker is exempt only when GitHub's own closingIssuesReferences for the pull request lists it, and only for a pull request into the default branch. The strict closing-syntax reader (indented code, setext and thematic-break boundaries) is gone: an exemption can no longer be broader than what GitHub does, and `Fixes: #N` / `Fixes owner/repo#N` now count. - Links are read leniently from the title, the description and every commit message, plus GitHub's closing list; references are ASCII digits and whole tokens (`#5abc`, `#５` are not references); `http://` issue URLs count. - A number that names no issue (GitHub's NOT_FOUND for repository.issueOrPullRequest) is treated as no issue instead of a failure; any other GraphQL error still fails. - At most 50 linked issues, 100 commits and 50 closing references are read; more fails without a lookup. One check run per pull request at a time. Sync: - One issue that cannot be read or written no longer stops the others or the pull-request reconciliation; failures are reported and exit 1 at the end. An issue whose links could not be read is never treated as free. - `neutral` / `skipped` count as passing; a check older than 30 days is not re-run (a push re-runs it). Override events are sorted by time. An endless comment thread never triggers a repeated notice. - Manual runs only from the default branch. Messages and /assign: - An override lists what it accepts; a not-completed blocker asks for a re-plan, not a wait; an unblocked issue that still carries needs-triage says so; a context-only reference is told to drop the keyword. - /unassign never reads dependencies; a missing summary or a closed blocker makes /assign read the blocker list and count from it alone. Docs: CONTRIBUTING (rules, limits, maintainer notes, the Actions policy prerequisite), code-review.md merge conditions, PR template, CHANGELOG (advisory until required), good-first-issue links exclude `blocked`, test module count 132.

…them Follow-ups for the issue-dependency mechanism that the review of #1035 deferred (#1039): - Read the title and the description through GitHub's own renderer (POST /markdown) and keep the prose outside <code>/<pre>; commit messages are read as plain text. Replaces the line-walker readers. - Record a maintainer's dependency-override in a bot comment (head commit and linked issues) from a new "Record dependency override" job; a new commit or a new link ends the override. - /assign says when the dependencies could not be read. - gh api --include: paging follows Link rel="next", transient read failures are retried honouring Retry-After, writes never are. - Reconciliation prefers check runs tied to the pull request; sync removes `blocked` from pull requests; a second unblocking gets a second notice; label history comes from the GraphQL timeline. - Sync every 15 minutes; a coverage floor of 90% for the three workflow scripts in tools/; runbook for renames, transfers, merge queues and a second maintainer in MAINTAINERS.md. - Polish: blob/HEAD links, release and limit wording, ANSI and invisible characters stripped from logged errors, a scaling ReDoS test.

…them (#1043) ## Summary Works through the fifteen follow-ups that the review of #1035 left for later. Each one is either implemented or closed with a reason. The owner made four decisions: - Item 2 records an override in a bot comment. - Item 3 waits for a second maintainer. - Item 10 runs the sync every 15 minutes. - Item 14 gives the three workflow scripts a coverage floor of their own. Fixes #1039 ## The fifteen items | # | Resolution | |---|---| | 1 | **Done, differently from the proposal.** A local CommonMark scanner would still be an imitation, so the description is now read as GitHub itself renders it (`POST /markdown`, `gfm`, this repository as context). `html.parser` keeps the prose outside `<code>` and `<pre>`, and every block boundary becomes a line break. The constructs listed in the issue all resolve as GitHub resolves them: a code span holding `<!--`, escaped backticks, abrupt comments, fences in quotes and list items, raw `<pre>`. GitHub's real output for 32 hostile samples is captured in `tests/fixtures/github_markdown/renders.json`. One behaviour changes: an inline `<!--` that never closes is now read, because GitHub shows it as text. The title and the commit messages are read as plain text: GitHub does not render a title as Markdown (an HTML comment or a fence marker shows there as written), and it closes issues from commit messages whatever they look like. The four line-walker readers are gone. | | 2 | **Done (owner's choice: bot comment).** A new *Record dependency override* job runs only when `dependency-override` is added. If a maintainer added it, the job comments with the head commit and the issues linked at that moment; it takes the title and description from the event payload, so an edit a second later is not accepted. The override counts only while the head is unchanged and the linked set is a subset of the recorded one. A new commit or a new link ends it, and the check says why. Only comments by `github-actions[bot]` count, so a person, or another app quoting someone, cannot forge a record. The required check `needs` the recorder (`if: !cancelled()`), so the record exists before the check reads it. | | 3 | **Closed with a reason (owner's decision).** With one maintainer, code-owner review would only add a bypass to every merge. MAINTAINERS.md now says that adding a co-maintainer turns on *Require review from Code Owners* for `development`. | | 4 | **Done.** When `/assign` cannot read the dependencies, the reply says so and tells the maintainer to check **Blocked by** before assigning (`DependencyReadError`). | | 5 | **Done.** `gh api --include` gives the headers. A list ends where GitHub announces no `rel="next"`, so an exact multiple of the page size costs no extra request. Endpoints keep their fixed `page=N` form, because GitHub's `Link` URLs use `repositories/<id>/…` paths outside the allow-list. The bounds that used to stop silently in `assign_on_comment.py` now warn or fail. | | 6 | **Done.** Reads are retried (GET, GraphQL queries, renders), 3 tries with 2 s / 4 s back-off. A retry happens on no answer, a 429 or 5xx, or a rate-limited 403, honouring `Retry-After` and the rate-limit reset up to 60 s. Writes are never repeated. This applies to both scripts. | | 7 | **Done (runbook).** A *Repository automation* section in MAINTAINERS.md lists what a rename or a transfer breaks: the `github.repository` guard, the Actions policy, branch protection and the project-board link. The guard's comment points there. | | 8 | **Closed with a reason.** No merge queue exists. The same runbook says to add `merge_group` before enabling one, or the queue waits forever for the required check. | | 9 | **Done.** Reconciliation prefers the check runs whose `pull_requests` name this pull request. It falls back to the latest run, since fork runs often name none. | | 10 | **Done (owner's choice: 15 minutes).** The cron is `2,17,32,47 * * * *`; the messages and docs say "within 15 minutes". | | 11 | **Done for pull requests; transfers closed with a reason.** `sync` removes `blocked` from open pull requests (in the reconciliation pass) and from closed ones (the closed list now keeps them). The token cannot write to the repository a transferred issue lands in, so CONTRIBUTING's maintainer notes say to remove the links and the label before transferring. | | 12 | **Done.** The unblock marker carries when `blocked` was last added (`…@<time>`), so an issue unblocked a second time gets a second notice. | | 13 | **Done.** Label history comes from GraphQL `timelineItems(last: 100, itemTypes: [LABELED_EVENT, UNLABELED_EVENT])`. The REST event pages are no longer read, so a long history cannot fail the check. | | 14 | **Done (owner's choice).** A new CI step and two gauntlet lines run the three scripts' own tests under coverage and require 90% across `tools/issue_dependencies.py`, `tools/assign_on_comment.py` and `tools/triage_gate.py` (today 95 / 94 / 100, 96 overall). `tests/test_guard_wiring.py` pins both lines, and a new test makes sure the full `pytest` run is not replaced by this subset. | | 15 | **Done, except the `gh` pin.** <ul><li>`contributing_url` points at `blob/HEAD`.</li><li>`MSG_RELEASED` says only that the person is no longer assigned.</li><li>`MSG_LIMIT` reads "You have N open assignments, and the limit is 2".</li><li>`_clean` strips ANSI sequences and non-printable characters, including bidi overrides.</li><li>A scaling ReDoS test follows `docs/standards/regex.md`: median of 5, a 10× input, a 3× tolerance. The small input repeats so timer noise cannot produce the flake seen in #72.</li></ul>The `gh` CLI stays unpinned: the scripts use only `gh api --method/--input/--include`, and downloading a binary in a job that holds a write token adds more to trust than a version drift on GitHub's own runner image costs. | ## Security notes - **The recorder job writes, but only comments.** It holds `contents: read` and `pull-requests: write`, runs only for a `labeled` event naming the override label, checks out one file from the default branch and executes nothing from the pull request. The required check stays read-only. - **No change to the Actions policy.** Both jobs live in `.github/workflows/pr-dependencies.yml`, the path the `pull_request_target` policy already allows. - **Concurrency moved to the check job.** The recorder is never cancelled by a burst of events. ## Testing - **Unit tests:** `tests/test_issue_dependencies.py` and `tests/test_assign_on_comment.py` cover every item (597 tests across the three workflow-script modules). - **Live read-only check:** run against the API before opening this PR: - the new GraphQL `label_changes` query on an issue and on a pull request; - `gh api --include` parsing of a 200, a 404 and a GraphQL error; - `Link` paging; - rendering and reading a description. - **Review round 1 (CodeRabbit):** the title is no longer rendered (it could hide a visible reference), and the full-suite wiring test rejects a narrowed CI `pytest` command. - **Full gauntlet:** the CLAUDE.md gauntlet passes locally (6,308 tests; every guard green; the new coverage step reports 96%). ## After merge - **Recorder:** check it on a real pull request: set `dependency-override`, see the record comment, push a commit, see the check turn red with the reason. - **Schedule:** confirm the first runs of the new 15-minute schedule. 🤖 Generated with [Claude Code](https://claude.com/claude-code) <!-- This is an auto-generated comment: release notes by coderabbit.ai --> <!-- coderabbit-ai-generated:v1 --> ## Summary by CodeRabbit - **New Features** - Dependency checks now recognize GitHub-rendered links in pull request descriptions, titles, commits, and Development links. - Maintainer dependency overrides are recorded against the current commit and linked issues. - Pull requests are automatically rechecked every 15 minutes, with updated unblock notices and `blocked` labels removed when dependencies are resolved. - Assignment workflows now handle pagination, transient API failures, and clearer error guidance. - **Documentation** - Updated contributor and maintainer guidance for dependency automation, overrides, repository changes, and validation requirements. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>

Turns dependencies between issues into a contributor-facing gate: a native Blocked by link drives a derived
blockedlabel,/assignrefuses blocked issues, and an Issue dependencies check fails a pull request that works on one. The check is advisory until branch protection lists it (see After merge).Related issues
